Rising from the River
The Corps of Engineers completed construction of a 20 Million cu yd dredged material containment facility in the Delaware River in 1990. The authors examine the performance of the geotextile...
A Texas-Sized SSO Solution
Houston is under the gun to control chronic overflows in its sanitary-sewer-collection system--a wet-weather problem that has plagued the city for years. For a problem this massive, the...
Seismic Isolation in Bridges
In the U.S., the use of seismic isolation in new bridge construction and retrofit projects has been growing as awareness of seismic risk has spread across the country since the 1971 San...
Putting Waste to Work (an Engineer's Obligation to the Environment)
With a limited supply of natural resources and overwhelming amounts of waste material overburdening the country's landfills, engineers are faced with tremendous challenges...

Human Extender: A Material Handling System
A human's ability to perform physical tasks is limited by physical strength, not by intelligence. `Extenders' are a class of robot manipulators worn by humans to augment human mechanical...
Developing Plans for Robotic Excavators
We would like a robot excavator that is able to excavate a volume of soil according to specification. To this end we have developed a general method that can be used to provide prescriptions...
Advancement of Material Handling Technologies for In-Place Asphalt Pavement Recycling
New technologies for asphalt pavement resurfacing are improving dramatically with the advancements being made to related equipment technologies. This paper focuses on the recent developments...
Demands and Satisfiers for Automation and Robotics in Construction: Differences Between Japan and the United States
The construction industries in Japan and the United States face problems of productivity, quality, safety, and skilled labor shortages. Automation and robotics are often proposed as solutions...
A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...
